How long have you had your display connected? The display goes through a 14-33 day learning mode where the unit is learning your elevation to adjust the barometric pressure and to give an accurate forecasting. If the unit has gone through the whole learning mode, we would recommend factory resetting the display to restart the learning mode. Thank you and have a great day!

Thanks Rachell for your reply...I guess it is in learning mode yet, but 1 questions abouta that...the HD dsiplay 06058, when setting give me some alternative to chose TIME ZONE, as I live in Argentina which one must I chose ? THANKS and MY BEST REGARDS !

Unfortunately, this unit is designed to function in the US, Canada, and Australia. This unit does not have the correct time zone for your area. The closest time zone is an hour ahead of your time (AST). Please let us know if you have any other questions. Thank you and have a great day!
